Holy cramps

I believe I had my first experience with Braxton Hicks? Serious cramping like menstrual cramps really low in my abdomen for 4 hours. Tried Tylenol, heating pad, no relief. Very slight spotting. Serious pressure like I had to poop but from the front and speaking of poop-tmi but have gone 4 times so far today. Feeling kind of better but exhausted. Scary to think this was just a glimpse of what’s to come. 😔 only 36 weeks so not ready for baby to be here yet. Glad I have a dr apt tomorrow! We got this!
